St141 modification thread

[CELICASUPRA7M]

my mistake, sorry. Thought it would be more simple

Suspension for daily driver?
I had pedders lowered springs and monroe gt-gas in mine.
The parts were cheap, suspension had a good ride, was not too low
and didn't draw cops attention.
ST141's look cool when lowered especially with 15" to 17" alloys and also because they've got sort of a little flare on the guards.

cheers,

That's why it's deceptively hard

No need to be sorry.

If any of you have any questions, shoot.

15" wheels with 0 or low negative offset suit these cars to a tee.

s14 4 piston brakes bolt up directly to the strut, you just need a spacer to correct the disc offset.



st141 strut, s14 calipers, s14 discs

^^^^ I agree. 15" wheels are much better. It just wouldn't look right fitting wheels that are too big and not proportional to the size of the brake assembly.

I'd love to own a Corona again, but maybe start with a Avante instead of the CSX.

cheers,

hmm i have jza70 wheels that i think my local engineer could redrill easily and safely.. 16x7 should fit well.. not sure of the offset tho

more details?

how does the rotor fit on the standard rotors are mounted to the hub etc...

id say that example has s14 hubs

[slide86]

that example is on my own car.....(ae86)

it has st141 hubs. s14 is five stud, so obviously its not s14 hubs, you can also see from that pic that the disc has been redrilled to 4x114.3. if they were s14 hubs then there would be no need to redrill and there would be an extra stud there.

the disc is simply a full floating style arrangement, it just slides on like many conventional brake setups.

the only thing not shown in the pic is the hub centric ring to ensure the disc sits correctly on the hub.

[ecko]

but afaik the st141 hub bolts to the disk the hub it on the disk but there it look like the disk is on the hub... how was that done..
also what master cylinder is used?

[slide86]

first, you need to do something bout your grammar, i can hardly understand that....

its the DISC that bolts to the HUB on a conventional st141 setup. it bolts BEHIND the hub.
- all you do is remove the hub and disc from the stub axle, unbolt the disc from the hub.
- refit the hub to the stub axle
- slide the s14 disc that has been redrilled onto the hub.
- fit the caliper

i used an r32 non abs master cylinder on my setup, but im not sure if st141 brake booster has the same stud pattern

[ecko]

okay i see..you mentioned a spacers? any details on this? and what size/offset wheels woulld i need to clear the brakes?
thanks mate very handy info, rep to you

For a cheap/basic upgrade RA60/SA63/RA65 Celica discs & calipers bolt straight on. I did this upgrade for $30 on my 1GGTE ST141 and you don't need to do anything custom - even the factory ST141 brake lines fit right up.

Sorry to be critical but the S14 conversion has been described as "bolt on" but given that the disc has to be redrilled, you need a spacer to correct the offset, and you need a spacer ring to make the disc fit the hub correctly it's about as hard as a brake conversion gets, save for the fact that the caliper bolts on without needing an adapter.

A lot of people get in trouble starting things and not knowing the full details, this is the perfect example of something that looks simple but can actually be quite expensive/difficult for those without the tools/know-how/access to a machine shop or someone to do it at cheap rates.

^^^^^^^^^^^^^^how easy is it to bolt a 1g into a st141?

[old_school_jap1]

alot of stuff is interchangeable between these coronas and the _a6_ series celicas and supras. helps when you need to get rid of all the borg warner crap
